Topologies in Computer Network Design
Computer network design needs good understanding of topologies like ring, star, bus and so forth. Designing computer network has to meet some rules and such rules are all called as topology. These days, Ethernet is the most widely used topology put in use which consists of peripheral cables and computers together in specific ways. It’s because of the reason that Ethernet is relatively affordable, easy to set up and use and also, fast. The truth is, Ethernet comes in two forms and these are fast and standard Ethernet.
Other topologies that you have to be aware of which can also be useful in creating a complex network are discussed in the next lines.
Number 1. Bus topology – basically, this type of topology is using backbone when connecting a device. Because of this, the backbone has cable which functions as a shared communication medium wherein other devices could be connected as well. As a matter of fact, this topology isn’t that hard to install and for the cabling, there aren’t many of it is needed. If you are using limited devices, they can provide you the best level of performance.
Number 2. Ring topology – in this kind of computer network design, there will be two neighbors for every device in relation to the communication. It’s for this that every data travels in the same direction whether it is counterclockwise or clockwise. If there is any failure in the cable, the entire network stalls and eventually fail.
For the communication process when you are using ring network, all devices have two neighbors. All the messages are travelling through a ring in same direction. If the cable or the device failed, then it’s going to break the loop that will take down the entire network.
Number 3. Star topology – for this topology, you will likely find this in residential properties. It is featuring a connection point like a hub switch or router and the devices are normally using UTP Ethernet to connect.
Number 4. Tree topology – for this kind of computer network design, it consist of various start topologies that are intersected onto a bus. This is providing outstanding expandability of network and it is a lot better than a bus or a star.
Number 5. Mesh topology – this particular computer network design makes use of routes concept. Messages are sent in this kind of topology are given on different paths to travel before it reach its destination. As a matter of fact, the internet is the most popular example of mesh routing.
